I have a Marantz SR4200 and have noticed a low level hum coming from the amp. It is also accompanied by a slight vibration of the unit. My first thoughts are a problem with the transformer, or maybe an earth problem. I have checked the power lead from the amp, and the amp only has 2 prongs for power transfer.
Am I right in thinking that this is missing the earth?
Is there anthing I can do to stop this hum and vibration?
Thanks,
Crisp
